Definition
Noun: * In computing, a pel is the smallest individual, addressable element or discrete unit that makes up a digital image or a picture displayed on a screen. It is a single point in a raster image.
Usage
The term pel is a technical abbreviation for "picture element." It is synonymous with the more common term pixel. It refers to the fundamental building block of a digital image. * The resolution of the monitor is determined by the number of pels it can display horizontally and vertically. * Each pel in the image file stores color information.
Advanced Usage
- The term pel is considered somewhat dated and is primarily found in historical or highly technical computing contexts. In modern usage, pixel is overwhelmingly preferred.
- It is used when discussing the granularity of an image, especially in relation to display hardware or image sensor technology.
- Early computer graphics dealt directly with manipulating individual pels.
